Flood is the most typical pure catastrophe in Nigeria; it’s a non permanent overflow of water onto land that’s usually dry.
Nigerians have at all times feared floods and with a superb purpose. The flood predictions indicated that elements of 121 LGAs in 27 States and the FCT fall inside the extremely possible flood threat areas, whereas elements of 302 LGAs in all of the 36 States of the Federation together with the FCT fall inside the reasonably possible flood threat areas. The elements of the remaining 351 LGAs fall inside the low possible flood threat areas. Nonetheless, the expected possible flood space protection in 2021 is predicted to be related however decrease in magnitude to that of 2020.
The Director-Common Nigeria Hydrological Companies Company, Engr. Clement Nze, stated in a press launch lately that the extremely most likely flood threat states are Lagos, Nassarawa, Anambra, Imo, Abia, Kwara, Yobe, Ekiti, Ogun, Delta, Taraba, Ondo, Enugu, Kaduna, Rivers, Ogun, Borno, and Katsina.
Nze famous that every one the flood occurrences had been triggered by poor drainage methods as localized rainfalls produce flash/city flooding, whereas River and Coastal flooding are but to happen.
As well as, some coastal States similar to Bayelsa, Delta, and Lagos are anticipated to expertise coastal flooding as a consequence of rise in sea degree and tidal surge and this might impression fishing, habitation, and coastal transportation.
By leveraging technological options similar to those described under, the nation can scale back the impression flooding has on the nation’s financial system.
Wi-fi Emergency Alerts (WEAs)
Collaboration with cell phone networks suppliers to make provisions for Wi-fi Emergency Alerts by the authorities is a viable approach of stopping disaster that comes from flooding. WEA will ship warnings if there’s a hazard to life close by similar to extreme flooding.
In an emergency, telephones or tablets will obtain an alert from the emergency providers, authorities departments, companies, and public our bodies that take care of emergencies with recommendation about tips on how to keep protected. These networks also can assist authorities talk simply with each other and with imperiled communities over social media.

This tech answer would assist in mitigating the impression floods have on residents sooner or later. Underwater drones also can assist responders study infrastructure and coordinate rescue efforts in closely flooded areas.
Flood Forecast Maps
Flood forecast maps are used to find out which areas are most liable to flooding utilizing distant sensors, elevation, proximity to our bodies of water, and different topographical knowledge. This tech answer can also be employed in evaluating if and when to rebuild infrastructure after a pure catastrophe, as some areas could have develop into too harmful to accommodate properties and companies after such incidents.
The map enabled German safety operatives to launch a profitable rescue operation on 15 July.
The Fast Response Water-Gate
Water-gate is a intelligent PVC gadget that makes use of the stress of oncoming water to stabilize itself. This basically signifies that the floodwaters are used to construct their very own dam.
Whereas costlier than sandbags, it has been confirmed to be a extremely efficient technique of containing flood injury. A single particular person can deploy the water-gate in a number of hours to guard a house whereas bigger units can be utilized to guard whole areas.
